SPECIFICATION forming part of Letters Patent No. 308,056, dated November 1.8, 1884-.

Application filed January W, 1884. (N0 model.)

To all whom it may concern Be it known that I, JAMES H. BUsELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Trimming Heels, of which the following is a specification.

My invention relates to improvements in the method of and machines for trimming heels by means of rotary cutters.

My invention consists. first, in trimming the heel by subjecting first one portion of the heel and then the remainder to the action of a rotary cutter, so that the two outs overlap and coincide between the seat and tread of the heel.

Heretofore the curves of the heel from tread to top lit't have been determined. principally, by the shape of the cutter in all heel-trimming machines known to me, although in. practice it has been common to partially trim the heels upon-the machine and afterward complete the trimming by hand.

The main feature of my invention consists in a new method of trimming heels by means of a rotary cutter, the novelty residing in shaping the heel around the top lift and also around the tread by means of a rotary cutter, the curve of the cutter fitting the curve of the heel for only a portion of its length, and the second cut overlapping the first to complete the trimming. This is best shown in Figures 3 and 5, which represent two styles of cut ters, each adapted to trim heels varying con siderably in size and style. In practice it is somewhat better to begin by trimming around the top lift and end by trimming around the heel-seat; but of course either cut may be first in some styles of heels, while in other styles this first cut must be around the top lil't. In certain styles of heels it is better in practice to use a separate rotary cutter for trimming around the heelseat, as illustrated in Figs. 4, 6, and 7. It will be clear that the cutter shown in Fig. 5 is in effect two cutters, one portion adapted for trimming the heel at and below the heel-seat, and another portion adapted for trimming the heel at and above the top lift or tread of the heel, while in Figs. 4, 6, and 7 the cutters are adapted for trimming only around the heel-seat and below it.

Fig. 1 is a perspective view of one form of cutter the top lift of the heel is held with its corner in the groove a of the tread-guide A, and the heel is turned until it is trimmed around the top lift and above it for the greater part of the heel. The shoe is then shifted to bring the rand-guide (1 into the rand, and the heel is trimmed around the heel-seat, and for some distance below it. In both operations the heel is properly rocked to give the curves desired from top lift to hcel'seat. -The randguide (I is close against the rotary rand-cutter y, as shown enlarged in section in Fig. 8, when the welt is to be taken out.

In Fig. 8 the rand-knife g is shown in one piece with one of the disks of the cutter, and this is the preferred way to make it, although it may, of course, be made otherwise. This way shown in 8 is old in rotary cutters for trimming sole-edges, although it is new with me in combination with a rotary cutter for heel-trimming made with teeth, .VllOSB cuttingedges are arranged to break joints, as shown, so that the outer end of each tooth acts as a guard to prevent too deep a cut by the cutting-edges of the adjoining teeth.

The tread-gun e (shown in Figs. 3 and 5) is composed of a disk of metal, A, having the groove (6 formed in it, and serves as an aid to the workman in presenting the heel to the cutter. One surface of the groove a is a rest for the tread of the heel, and the shorter surface or groove (0 is flush with the adjoining cuttingedges of the cutter B. This tread-guide is new in itself, and is adapted for use with most of the heels which are trimmed with rotary cutters.

low heels called s rin heels it is desirable to have a counter-support, and this I provide by arranging the heel-rest F, so that it can be adjusted at the heelseat end of the out- In certain classes of heels, especially those ter, as shown in Figs. 6 and 7. The endf of the rest F has its upper part within the circle formed by the heel-seat end of the cutter, and its lower part without that circle, the work.- man resting the upper of the shoe above the heel on the face of part f, and thereby greatly facilitating the proper presentation of the h eel to the rotary cutter.

In certain classes of heels a heel-rest is desirable at the top-lift side of the cutter when trimming around the heel-seat and just below it. This combination is shown in detail in Fig. 4, and also on the shorter shaft of Fig. 1.

The heel-rest d is a disk of metal rounded on its edge and having a slot through it to receive the shaft. It is adjustable in and out by means of slotted arm d and thumbscrew d, as shown in Fig. 4, and is preferably pinned at d. to arm (7?, so that it may more readily find the lowest part of the curve. of the heel. It aids the workman in presenting the heel to the heel-seat trimmer D.

For trimming certain classes of heels the s oe should be supported by means of a heelpin, it. when a last is used mounte upon a rod. I-I, adjustable as to length and capable of motion in all directions on ball h. \Vhere 110 last is used the pin it is forced into the inner sole near the middle of its heel portion, or a support, It, circular in trosssection, but otherwise heel-shaped, is used on pin h, the purpose being to admit of the shoe being moved on the heelpin h as an axis The heel-rest Fis removed when support H is used.

In Fig. 3 the cutter is provided with an upper guard, K, instead of a mudguard, as in Figs. 5. 6, and 7. This upper guard, K, i a disk of metal which projects slightly beyond the adjoining cutting-edges, so that this projection will come in contact with the uppe. and effectually prevent the upper from coming in contact with the cutter while rocking the shoe to give the proper shape to the heel.

In Fig. 1 the machine is shown asit is most commonly usedthat is, the workman begins by -esting the breast of the heel on the part f of heel-rest F and presents theside of the heel near the breast to the tool, turning it and holding it in contact with the restf and guiding it by the tread-guide A until the edge ofthe top lift and a portion of the surface above it is trimmed. He then repeats the operation, except that in making the second out he guides the heel by the rand-guard d;

Vhen the shoe is supported by the heel'pin h,the workman usually begins near the breast and trims from breast to breast, and also when the shoe is supported b' the counter, the rest being at one side of the cutter, as in Figs. 6 and 7.

I am aware of the United States Patent to Tayman, No. 136,790, dated March 11, 1873, which shows a rest for the edge of the heel or sole; but that rest is parallel with the axis of the cutter, while my rest must be substantially at right angles with that axis. The Tayman patent also shows a c0unter-rest, but its acting surface is all within the circle of the heel seat end of the cutter, while it is essential that my rest shall extend so that itslower end will project beyond that circle. I therefore disclaim all that is shown in that patent.

I claim as my invention 1. The method of trimming boot and shoe heels, herei'nbefore described, consisting in making two cuts with rotary trimmers, which cuts overlap between the seat and tread of the heel, one cut trimming around the top lift and above it, the other around the heel-seat and below it, as set forth.

2. In combination with a rotary-cutter, a tread-guide consisting of a disk of metal having an angular groove formed in its periphery, one wall of the groove forming a rest for the tread of the heel, and the other and shorter wall of the groove being flush with the ad joining cutting-edges of the rotary cutter and forming a guide, so that the lower part of the heel is trimmed to conform to the shape of the lower corner of the top lift, substantially as and for the purpose set forth.

3. In combination, a "rotary cutter and a rest for the heel arranged at that side of the cutter which comes nearest to the top lift or tread of the heel when the heel-seat is being trimmed, substantially as described.

4. In combination with a rotary cutter, the rotating counter-guard K, having a rounded corner next the teeth of the cutter, and adapted to prevent contact of the upper with the cutter without marking the upper. substantially as set forth.

5. In a heel-trimming machine, the combination of a rotary cutter for trimming the heel-seat and a rotary rand-knife with a randguide and a heelrest at right angles with the axis of the cutter, substantially as set forth.

6. A rotary trimmer for heels, having at one end a tread-rest adapted to receive the corner of the top lift and at the other end a guard, substantially as set forth.

7. The counter-support f, in combination with the rotary cutter, the supportf lying across the heel-seat end of the eutterthat is, its upper end being within the circle formed by the heelseat end of the cutter, while its lower end is without that circlesubstantially as described.

8. The combination, with a rotary cutter, of a rotary rand-guard and a support for the edge of the heel arranged at right angles with the axis of the cutter, substantially as set forth.

9. In combination with a rotary cutter, the

heel-pin h, for supporting the shoe, secured to rod H, capable of universal motion, sub stantially as and for the purposes set forth.
